My understanding of the difference is the following:
Image of God: These are the parts that make up a human being that is different from any other living thing: Body, Soul, and Spirit.
Body: We were formed from the dust of the earth that was later cursed through sin. Adam and Eve ate the fruit that became part of her body and corrupted it. This part of Human beings will be changed into the incorruptible before entering heaven. However, the body is still important 1 Cor 6:19 “Or do you not know that your body is a temple for the Ruach HaKodesch (Holy Spirit) who lives inside of you, whom you received from God?” You do not belong to yourselves; for you were bought at a price. So use your bodies to glorify God.” Rom 12:1-2 “I beseech you therefore, brethren, by the mercies of God, that you present your bodies as a living sacrifice, holy, acceptable to God, which is your reasonable service and do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God.”
Soul: A soul is having a Mind, a Will, Feelings, Morality, and Purposes. God gave Adam and Eve free choice and He had a purpose for them to rule the earth and have fellowship with them, His first Covenant. This is the area that satan targeted in the Garden of Eden. He challenged Eve’s mind and her will. Gen. 3:5 “God knows that on the day you eat from it your eyes will be opened and you will be like God knowing good and evil.” Tempting humans with knowledge of his evil. “v6: the tree was desirable for making one wise, she took from its fruit and ate”. They already knew good as God was good and they were living in His garden, having fellowship with Him. They emotionally reacted (had shame) and the purpose that was given to them was cursed (rulership, bearing children, cultivating the earth). Their morality was affected as they gave in to lies and blame-shifting. Their disobedience brought death to the earth. Adam and Eve were expelled from the garden. To prevent humanity from accessing the Tree of Life and living in their sin forever (God still showed grace), God stationed “cherubim and a flaming sword flashing back and forth to guard the way to the tree of life” (Genesis 3:24). God also gave the promise of a redeemer through Adam and Eve’s descendants. Jesus warned that Human beings should guard their soul of temptations. “Matthew 10:28 - And fear not them which kill the body, but are not able to kill the soul: but rather fear him which is able to destroy both soul and body in hell.” Matthew 16:26 - For what is a man profited, if he shall gain the whole world, and lose his own soul? or what shall a man give in exchange for his soul?”
Spirit is what was breathed into man by God. Genesis 2:7 “God formed Adam from the dust of the ground and breathed into his nostrils the breath of life, so that he became a living being.” 1 Corinthians 15:45 “So also it is written, The first man, Adam, became a living soul (human being). The last Adam (Yeshua) became a life-giving spirit.” The Spirit is the essence of life which belongs to God and will return to God when we die. Jesus gave up His “spirit” on the cross Luke 23:46.
Likeness of God: This refers to a state of being (represented in manner/behaviour), not to be confused with attributes that only God can possess (omnipresence, omnipotence, etc.). To know the likeness of God we look to Yeshua (Jesus) and the Holy Spirit (Ruach HaKodesch) as examples. The indwelling of the Holy Spirit gives humans God’s manner/behaviour... His likeness Galatians 5:22-23 “But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness and self-control.” Jesus exemplified these behaviours. Adam and Eve gave up their self-control and were rebellious (opposite of faithfulness) and pursued the knowledge of evil (opposite of goodness) and therefore corrupted the likeness of God in themselves.
